The Detroit-born rapper filmed a four-minute-and-34-second long video, which debuted during the awards show. Eminem, whose given name is Marshall Mathers, blasted Trump for everything from ignoring tragedies in favor of "causing a Twitter storm" to "support for the Klansman" and slandering Hillary Clinton. He also refers to Trump as "this racist 94-year-old grandpa" in the profanity-filled freestyle rap filmed in a parking garage in Eminem's home city.

Within hours of airing on YouTube, it was already the No. 1 trending video with more than 1.5 million views.

After Eminem picked up on Trump's feud with NFL players who kneel during the national anthem in protest of racial injustice, former San Francisco 49ers quarterback Colin Kaepernick, who is largely credited for starting the protest movement, tweeted a link to the video.

"I appreciate you Eminem," he wrote alongside the link.

Other rappers chimed in, including Sean "Diddy" Combs, who tweeted, "This is for Collin (sic) ball up a fist!!"
